stat_prefix

(string, REQUIRED) The human readable prefix to use when emitting statistics.

enable_sql_parsing

(BoolValue) Controls whether SQL statements received in Frontend Query messages are parsed. Parsing is required to produce Postgres proxy filter metadata. Defaults to true.

terminate_ssl

(bool) Controls whether to terminate SSL session initiated by a client. If the value is false, the Postgres proxy filter will not try to terminate SSL session, but will pass all the packets to the upstream server. If the value is true, the Postgres proxy filter will try to terminate SSL session. In order to do that, the filter chain must use starttls transport socket. If the filter does not manage to terminate the SSL session, it will close the connection from the client. Refer to official documentation for details SSL Session Encryption Message Flow.
